What is a coaxial cable standard? I thought it was cool after watching it

Introduction: Today, the editor specially introduces to you what the standard of coaxial cable is. Before introducing the standard of coaxial cable, naturally let’s first introduce what is coaxial cable.

What is coaxial cable?

For a clearer understanding, we can divide coaxial cables into 50Ω baseband coaxial cables and 75Ω broadband coaxial cables according to different uses. The baseband cable can be further divided into thin coaxial cable and thick coaxial cable.

From an objective point of view, coaxial cable refers to a cable with two concentric conductors, and the conductor and shielding layer have the same axis.

After understanding the concept of coaxial cable, let’s take a look at the standard of coaxial cable.

The editor learned about the standard of coaxial cable from the relevant standard manufacturer: The model is CC, the number of cores is odd, the sheath material is PTFE or FEP, the shape of the material is round wire, the maximum outer diameter of the wire is 2.5mm, and the insulation thickness is 1.1mm.

Let’s talk about the standard and structure of video coaxial cable:

Video coaxial cable adopts the GB/T14864-1993 national standard. The coaxial cable is divided into four layers from the inside to the outside: plastic insulator, mesh conductive layer and wire sheath, and central copper wire.

The official coaxial cable implementation standard is GB/T14864-1993. Distribution cables and office cables are generally HJVV? HJVVP? HPVV1. The coaxial cable implementation standard is GB11327-89.

Finally, let’s popularize the model specifications and range of coaxial cables: (This may not be all, but the editor will try to list what I know.)

HYAT, the city’s communication cable: Solid copper core, polyolefin insulated filled moisture barrier, polyethylene sheath.

HYA53 local communication cable: solid copper core, polyolefin insulated moisture barrier, polyethylene sheath, steel-plastic tape armored polyethylene sheath.

HYAT53 local communication cable: solid copper core, polyolefin insulated filled moisture barrier, polyethylene sheath, steel-plastic tape armored polyethylene sheath.

City communication cable HYA23: solid copper core, polyolefin insulated moisture barrier, polyethylene sheath, steel tape armored polyethylene sheath.

City communication cable HYAT22: solid copper core, polyolefin insulated filled moisture barrier, polyethylene sheath, steel tape armored PVC sheath.

In fact, most of them are the same, but there are some small differences. When choosing, you should figure out the model you really need in that situation.

Conclusion: The information about coaxial cables has been introduced here. You should not be so confused when choosing coaxial cables in the future. I hope it will play some role. Finally, I wish everyone can have a house that suits them best.
